STRAW-STACKING ATTACHMENT FOR THRASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 449,556, dated March31, 1891.

Application filed October 21,1890. Serial No. 368,777. (No model.)

To all whom t may concern.-

Be it known that I, AMos P. MILLER, a citizen of theUnitedStates,residing at El Dorado, 1n the county of Preble and State of Ohio,have invented a new and useful Straw-Stacking Attachment forThrashing-Machines, of which the following is a specification.

This invention relates to straw-stacking yattachments forthrashing-machines; and it has for its obj ect to construct a device ofthis class which may be mounted transversely at the rear end of themachine, so as to carry the straw oft' to one side.

The invention consists in the improved construction, arrangement, andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims. In the drawings hereto annexed,Figure 1 1s a plan View showing my improved straw- .carrier attached tothe rear end of a thrashing-machine. Fig. 2 is a sectional view takentransversely through my improved carrier and showing the rear end of athrashing-machine in elevation. Fig.3 is a sectional view takenlongitudinally through the carrier and looking toward the machine. Fig.4 is a sectional view taken on the line 4 4 in Fig. 1. Fig. 5 is a planview of the carrier detached from the thrashing-machine.

Like numerals of reference indicate like parts in all the figures.

My improved straw-carrying attachment is composed of an endlesscarriersuitably mounted upon a trough, which is constructed in the usualmanner of side pieces 1 1, connected by a bottom piece 2, and providedat their ends with bearings for the shafts 3 and 4, which are providedwith drums or pulleys 5, supporting the endless belts 6, which areconnected by slats 7. The sides of the trough may be provided withguard-rails 8, which may be readily mounted detachably in staples 9 uponthe sides of said trough, the guard-rails being provided with bracketsor stakes 9, to engage the said staples, as will be seen in Fig. 2 ofthe drawings. One side of the trough, which in practice is nearest tothe thrashing-machine, is provided with laterally-extendin g brackets11, having bearings for a shaft l2, the greater portion of which issquare in cross-section.

Upon one end of the shaft 12 is mounted a bevel-gear13, meshing with apinion 14 upon one of the shafts 4. Upon the square portion of the shaftis mounted a sprocket-wheel 15, having a collar 15, and which may beconnected by a chain 16 with a drive-wheel upon the thrashing-machine,from which motion may thus be transmitted to the endless carrier. Thesprocketwheel 15 is longitudinally adjustable upon the shaft 12, and maybe retained securely at any desired adjustment by means of a setscrew 17extending through the collar 15 of said wheel.

To the under side of the discharge end of the thrashingmacnine issecured a horizontal arm or bracket 18, which extends rearwardly andwhich is connected by means of inclined braces 19 with the sides of themachine. The arm or bracket 18 is provided with vertical perforations20, through which pass the hookbolts 21, the lower ends of which areprovided with thumb-nuts 22. To adjust my improved straw-carrier inposition for operation it is mounted upon the arm or bracket 18 betweenthe hook-bolts 21, which latter are caused to engage the upper edges ofthe side pieces of the conveyer-trough', which latter may then be firmlysecured by tightening the thumbnuts. The outer end or ends of theconveyertrough are connected by means of ropes or chains 23 with hooks24 upon the upper side of the machine,` thus bracing the carrier inposition for operation and also enabling its outer end to be raised whenit is desired to place the carrier in an inclined position.

The discharge-chute of the thrashing-machine is provided with a bracket25, which projects from the floor of the same rearwardly over thetransversely-arranged stacker, so as to deposit the straw upon thelatter in any position to which it may be adjusted.

My improved transverse stacker is intended to be used as supplemental tothe ordinary upwardly and rearwardly inclined stacker, which latter isin practice intended to receive the chaff that may be blown out throughthe tail end of the machine, while the transversely-arranged stackerreceives the straw and carries it off to the mow or barn. The transversestacker is intended to be arranged directly above the ordinary staker.

The stacker which forms the subject of my IOO invention is capable ofbeing,l adjusted transversel y with relation to the machine to which itis attached, the sprocket-Wheel l5 being longitudinally adjustable uponthe shaft l2, so that it may be readily moved to the position Which itis desired to occupy.

From the foregoing description, taken in connection with the drawingshereto annexed, the construction, operation, and advantages of myinvention will be readily understood.

The construction ot my improved stacker is simple and inexpensive, andit maybe readily applied to any ordinary thrashing-machine withoutchanging' the construction of the latter in any particular, except toprovide it with the horizontal supporting-bracket 18, having the boltsby means of which the trough of the carrier is secured in position ioroperation.

The device is especially useful l'or thrashing` tlax and the like, whereit is desirable to separate the straw from the chaff and to convey it toa separate place ol' deposit.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

l. As an improvement in straw-stackers, the herein described endlesscarrier, the frame of which is provided at one side withlaterally-extending brackets, in combination with a shaft journaled insaid brackets and having a longitudinally-adjustable sprocketwheel, andprovided at one end with a bevelgear meshing` with a pinion upon theshaft `at one end of said endless carrier, substantially as set i'orth.

2. In a straw-stacker for thrashing-niachines, the combination of thelframe consisting ofside pieces connected by a suitable bottom piece,the shafts journaled at the ends of said side pieces and having drums orpulleys, the endless bands mounted upon the latter and connected bytransverse slats, the guard-rails having; stakes adapted to engagestaples upon the side pieces, brackets extending; laterally from thelatter, a shaft journaled in said brackets and having alongitudinally-adjustable sprocket-wheel, and a bevel-gear mounted uponone end of said shaft and meshing,` with a pinion upon the sha-ft at oneend of the frame, substantially as set t'orth.

3. The combination, with a thrashing-machine having` arearwardly-extending arm or bracket, of a straw-stacker mountedadjustably upon said bracket' transversely to the thrashing-machine, thebolts 2l and chain 23 for securing the said stacker-frame adjustablyupon the said bracket, and a sprocketwheel mounted adjnstably upon thedriveshaft oi' the carrier and adapted to receive motion from thethrashi11g-machine, substantially as set forth.

In testimony that I claim the foregoing as myown I have hereto aiiixedmy signature in presence of two Witnesses.

AMOS I. MILLER.
